Printing a canopy plug

[pedwards2932]

I have been sharpening my Fusion 360 skills so I can make a plug for vacuum forming a Super Chipmunk canopy.  Fairly decent learning curve but the skills I learned will allow me to make just about any canopy

Good work. I have a couple of questions.  Will the surface need smoothing before use and will the heated plastic damage it?

Last one I did I vacuum formed plastic over it and glued that on the plug.  That smoothed it out.  With this one I will probably shoot some primer on it and sand it a bit.  You have to a little careful with the heat but I am using 4 mil plastic so there shouldn't be a lot of heat transfer
